Kit Includes

✔ 184mm / 7.25" Single-Disc Clutch (ultra-lightweight, only 2.8kg)

✔ 184mm / 7.25" Ultra-lightweight Flywheel only  2.95kg

Component Features

Flywheel

• Weight: only  2.95kg
• Material: Forged CrMo steel, nitriding heat-treated
• Hardness: HRC 58–62 → over twice as hard as standard flywheels
  → Prevents wear on starter ring gear in high-compression engines
• Longevity: High surface hardness = extended service life & reliability
  

Clutch Cover

• Material: Forged 6061-T6 aluminum, hard anodized
• Construction: Steel-riveted legs for near-lifetime durability. Hardened steel thrust buttons/rivets offer a smooth and durable surface for the clutch cover legs, pressure, and floating plates.
• The tightening torque for the cover-to-flywheel bolts (M8x1.25, grade 12.9) is 41 Nm.

Top/Pressure Plate

• Material: Forged chromoly steel, cryogenically treated (in some applications)

Sintered Clutch Disc — Ø184 mm (7.25")

• Material: Proprietary blend of sintered metal compounds, engineered with precise manufacturing tolerances
• Standard version design: Three large friction pads for optimal engagement and reliability.
• Hub: Machined from forged chromoly steel and induction hardened for maximum strength and wear resistance
• Customization: Available on request (e.g. custom spline)

Clutch release bearing + specific support

• Bearing: racing-grade quality release bearing, essential for any race clutch to withstands extreme mechanical loads and high working temperatures
• Specific support

Flywheel to crankshaft bolts 

Key Features & Benefits

✔ Rated for 400+ hp / 450+ Nm in single-disc configuration, depending on clutch setup (diaphragm spring pressure and clutch disc friction material).

✔ Significant weight reduction vs OEM
→ Faster acceleration
→ Better throttle response
→ Improved handling & braking

✔ Improved shifting at high RPM

✔ Long lifespan of friction components → low replacement cost

✔ Plug & Play → No modifications required

✔ Better Pedal Feel & Modulation
Stick-up adapter ensures proper alignment of the release bearing for consistent feedback

Depending on the modifications already made, an adjustment may be necessary.
